25510512 ÷ 720 
The aim is to understand the frequency of 720 in 25510512.

Moving on to step 1:
When dividing 2 by 720, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 720

Advancing to step 2:
720 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 720

Step 3:
255 divided by 720 is 0 with a remainder of 255.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 255, we get 255.
Bring next digit (1) of the dividend behind the 255 and repeat the process: 2551 / 720

Step 4:
When dividing 2551 by 720, we get 3 with a remainder of 391.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2160 from 2551 to get 391.
Append the next digit (0) from the dividend to 391 and continue with: 3910 / 720

Advancing to step 5:
When dividing 3910 by 720, we get 5 with a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
The remainder is 310 after subtracting 3600 from 3910.
Include the next digit (5) from the dividend after 310, then repeat: 3105 / 720

Step 6:
When dividing 3105 by 720, we get 4 with a remainder of 225.
Write down 4 as next digit of the result. 
Result so far: 354.0
Subtract 2880 from 3105 to get 225.
Grab the next digit (1) from the dividend, add it to 225, then carry on: 2251 / 720

Let's proceed to step 7:
When dividing 2251 by 720, we get 3 with a remainder of 91.
Write down 3 as next digit of the result. 
Result so far: 3543.0
If we subtract 2160 from 2251, we get 91.
Include the next digit (2) from the dividend after 91, then repeat: 912 / 720

On to step 8:
The number 720 fits into 912 1 times, leaving a remainder of 192.
Write down 1 as next digit of the result. 
Result so far: 35431.0
The remainder is 192 after subtracting 720 from 912.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 9:
1920 divided by 720 is 2 with a remainder of 480.
Write down 2 as next digit of the result. 
Result so far: 35431.2
If we subtract 1440 from 1920, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 10:
720 can be fit into 4800 6 times, resulting in a remainder of 480.
Record the quotient 6 as the next digit in the result. 
Result so far: 35431.26
If we take 4320 away from 4800, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 11:
When dividing 4800 by 720, we get 6 with a remainder of 480.
Use 6 as the next digit of our solution. 
Result so far: 35431.266
If we take 4320 away from 4800, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The quotient of the division is 35431.266, and the remainder is 0.048.
